"Ranunculus bulbosus", commonly known as St Anthony's turnip or bulbous buttercup, is a perennial weed of the Buttercup Family. It has attractive yellow flowers, and deeply divided, three-lobed long-petioled basal leaves. Bulbous buttercup is known to form tufts.

The stems are 20-60 cm tall, erect, branching, and slightly hairy flowering.RH Uva, JC Neal and JM Ditomaso (1997) "Weeds of The Northeast", Cornell University Press, Ithaca, NY. pp. 294-295] There are alternate and sessile leaves on the stem. The flower forms at the apex of the stems, and is shiny and yellow with 5-7 petals. The flowers are 1.5-3 cm wide. The plant blooms from April to July.

Bulbous buttercup gets its name from its distinctive perennating organ, a bulb-like swollen underground stem or corm, which is situated just below the soil surface. After the plant dies in heat of summer, the corm survives underground through the winter.Although the presence of a corm distinguishes "Ranunculus bulbosus" from some other species of buttercup such as "Ranunculus acris", the species also has distinctive reflexed sepals. Other common names for bulbous buttercup include: St. Anthony's turnip, blister flower, and bulbous crowfoot.

Cultivation and uses

Bulbous buttercup grows in lawns, pastures and fields in general, preferring nutrient-poor, well-drained soils. Although it doesn't generally grow in proper crops or improved grassland, it is often found in hay fields [ [http://www.ppws.vt.edu/scott/weed_id/ranbu.htm Bulbous Buttercup: "Ranunculus bulbosus"] ] and in coastal grassland. The native range of "Ranunculus bulbosus" is Western Europe between about 60oN and the Northern Mediterranean coast. It grows in both the eastern and western parts of North America, as an introduced weed. [http://www.gardenorganic.org.uk/organicweeds/weed_information/weed.php?id=70 HDRA Weed management]

Buttercups contain poisons 1% glycoside ranunculin in corm, and are avoided by livestock. Note however that the poisons of buttercup are lost upon drying, so any hay containing bulbous buttercup is safe for animal consumption. Protoanemonin is an irritating antibiotic, formed from enzymatic breakdown of ranunculin.

In spite of its toxic nature, this plant is listed as an herbal remedy. Used in Homeopathy for subepidermal blistering of the skin especially in summer. [ [http://homeoint.org/books/boericmm/r/ran-b.htm Ranunculus Bulbosus - Homoeopathic Materia Medica - By William Boericke ] ]
